Locate family - CHRISTOFF

I want to locate my grandfather's family in Bulgaria. His name was Grozdan Vascelle Christoff, born in 1894 in or around Lovech. He purchased a farm around Lovech in 1905 and worked it for 4 years. He left Bulgaria at age 15 years and arrived in the United States in 1909 at Ellis Island. One of his brothers purchased the farm from him a few years later. I think his mother's name was Mary and she died in 1895 and his father died around 1908. He had a nephew named Christo Minchev Donchev who had 2 children and lived in Ditchin and operated heavy machinery. Another nephew (the first nephew's brother) worked at the cooperative union and had a daughter named Milka that had heart trouble. I have been told that Grozdan Vascelle Christoff's father's family name may have been Bugdonoff although this may not be correct. Thank you for any assistance.
